Ubuntu :: System After Grub2 But Before Desktop Loads?
Sep 10, 2010
The screen will show a blinking cursor for a few seconds. The keyboard works and a signal is found for the speakers. Then the 'Ubuntu' loading screen will show but at this point the screen would freeze and the keyboard will cease to function. At this point I have to reboot from the on/off switch. It can take several attempts before the desktop will load, or if I'm lucky, it'll load up first time. I've had this problem since 9.10. I'm not quite sure why it's taken me this long to attempt to sort it out.

Just recently installed fedora 11 64-bit on my laptop. Everything was fine until today. Everytime I boot up, it crashes right after the desktop loads. Everything is loaded except the area where the running programs are on the taskbar is just one big white block. And a bubble popup says "New SELinux security alert. AVC denial." but everything is frozen. Can't move the cursor or use keyboard. and nothing is happening on the screen. Completly frozen. Anybody have any ideas on what is wrong and how to fix it?

On this dual-boot machine I have Ubuntu installed on hd0 (/dev/sda), Windows 7 is installed on hd1 (/dev/sdb). The mbr for Ubuntu is on /dev/sda1. After installing Windows I went through the steps to reinstall grub2 on /dev/sda1, but Windows 7 kept loading. So I went ahead and upgraded to 10.04, expecting the upgrade to overwrite the correct MBR, but this didn't work either. When I was looking at the advanced options in the 10.04 installation I noticed Windows 7 had an MBR in /dev/sdb2. If I installed grub2 to this partition should it overwrite 7's bootloader and allow me to load from grub2? Or is there something else I should be looking for to resolve this problem?

As a big supporter of Ubuntu, after installing Ubuntu 10.10 on my mums laptop i decided to also install it on my sisters Acer Aspire one netbook.
The specific netbook had pre-installed Win7 starter. Everything went really smooth with the installation with ubuntu 10.10, Grub menu was also loading pretty well but when i chose to load on windows it loads the recovery partition of the hard drive.
The issue is that the netbook, like most netbooks and laptops, has a hidden partition which is used to recover Windows on the system. My Grub2 loader added this partition as an option to load windows with result me not be able to boot on windows ...well i do can load but it loads the recovery of windows.

So I have used ubuntu for about 2 years now, and this has never been an issue. Basically my trackpad(touchpad) on my laptop stops working when the wallpaper and other gui aspects load. The mouse works in windows and works in ubuntu for a few seconds while the screen is still black and gui is loading. So I know ubuntu does know it exists.
This problem occured after watching a movie and ubuntu froze up. Also while watching the movie I had the trackpad disabled, which might have something to do with my problem. (I have a hpdv6500 which has a button on the trackpad to disable it. I did no software tricks or hacks to do it). After resetting my computer the problem existed and persists every time I turn it on and off. So does anyone have any experience with such a problem or maybe how to reset the settings of the mouse?

I need one, cause I know this is "So easy, a cave-man could do it" (and I can't) yikes.
I need a start up script to execute AFTER my desktop loads. It's for display resolution. I've added the same script in 3 places, and all will execute, but not until I do it manually. It's being over-written by another function...
1 script in /etc/gdm/Init/Default (as per Wiki page, which has a syntax error I found yesterday):
Quote:
#!/bin/sh
# Stolen from the debian kdm setup, aren't I sneaky
# Plus a lot of fun stuff added
# -George
[Code]....
Can I create a run level 7, like rc7.d, that will execute after the desktop loads (and everything else)? I symlinked the second script to level 5 rd5.d, and it didn't go through. I haven't tried level 6.

I just built a server, which displays 8 cores in the i7 processor. However, because of the 2 threads per core, it shows up as an 8 core system. When viewing htop, it shows system loads at 0.29,0.18, and 0.13 for respective averaging times. How would I calculate actual system load for this processor? Would I divide the average by 4 or 8? Or, is there another method?

As stated in the subject when I click on partition in Places or try to open a folder e.g. by selecting open containing folder in transmission the system will load music player instead of nautlius. Is this some kind of problem with file associations??

my data resides in a partition sda2 - in a logical volume lv_root.unless I'm wrong lv_root contains the information on how to load the partition.so superficially it seems the partition must be loaded bofore we get the info on how to load it.

Where does one look in terms of diagnostics after a system lockup and hard reset? For example, one of my computers, running Fedora 14 i686, has taken to locking up quite a bit lately. My only way out is a hard reset. Now, once the thing is booted back up I'd like to try to figure out where the problem lies. Where do I look? Will any of the log files reveal anything relevant to me? If so, what sort of things would I be looking for. Keywords?
This same box also locked up when I had Fedora 14 x86_64 installed. I had read that there were some issues with the newer 64 bit kernels that were causing lockups and / or extremely high loads. This is why I switched back to the 32 bit version, 2 days ago to be exact. The box gets little use. It's a toy really and not my main "daily use" computer. It is, however, running folding@home. Maybe that's where the problem is. About 15 minutes ago I called home and had my wife reset the box, then I logged in from work and stopped the folding service. I'll have to see if it locks up without folding running. Folding was running on this box when I had the 64 bit version installed also.

My Dell poweredge server running CentOS 5.4 and booting kernel-2.6.18-164.15.1.el5. All boot processes seem okay and the graphical screens for CentOS operate, but just before the desktop loads the screen goes blank and the arrow/cursor is being circled by small spheres. This remains indefinitely. While the arrow is being circled, here are the results of 'getinfo.sh device'

I've read the various Grub2 posts and even the guide, but unfortunately for me I can't seem to come up with an answer to my problem. I installed Ubuntu 9.10 on a new hard drive on a friends laptop, but I have problems with the system hanging on the Grub2 bootup.I'll post the screen
recordfail=1
if [ -n ${have_grubenv} ]; then save-env recordfail; fi
set quiet=1
insmod ext2
set root=(hd0,1)
search --no floppy --fs-uuid --set ac1b1d46-bac1-4140--953e-70a8a61be8b0
linux /boot/vmlinuz-2.6.31-14-generic root=UUI=ac1b1d46-bac1-4140-953e-70a8a61be8b0 ro quiet splash
initrd /boot/initrd.img-2.6.31-14-generic
If I hold down the left shift and then press E to edit and remove the search --no floppy line entirely then press ctrl-x the system boots just fine. I then opened up a terminal and did sudo update-grub to try that but it didn't fix it. Is this a problem in my bios looking for a floppy, I tried with the boot from floppy enabled and disabled (but always as the 3rd boot option) the floppy is not installed. Is there anyway to edit the file and save it so it will boot up? I was trying to research that and could not come up with it.

As a long time Red Hat/Fedora user, I'm quite new to the Ubuntu/Debian culture, and/or, to the Grub2 specific behavior.I'd like to see Grub2 system selection menu at every boot time even if I only have a single operating system, Ubuntu 9.10, on my hard drive. What should I do fot this purpose?

I've been using Ubuntu 9.10 for a while now, and i've started to look at other distros of linux. I found PClinuxOS which seemed decent and decided to install it alongside my Ubuntu 9.10 and Windows Vista. The bootloader that came with PClinuxOS recognised my Vista OS, but not my Ubuntu.long story short, i recovered Ubuntu's GRUB becasue i had already edited it to my liking. GRUB found the PClinuxOS partition and added it to the menu. Vista and Ubuntu start fine, but when i try to select the PClinuxOS option, i get this message-type-thing:
[linux-bzImage, setup=0x3a00, size=0x1f9110]vga=788 is deprecated. useset gfxpayload=800x600x16, 800x600 before linux command insteaderror: no such partitionI don't really know, but it almost sounds like GRUB is trying to find the linux kernel, but it cannot connect to the partition for some reason. I have been extremely pleased with Ubuntu, so I really don't need another distro, but I'd like to know how to fix this

Been using Linux for many many years but Grub2 is annoying the heck out of me at the moment.
My home desktop PC is set up as follows:
/dev/sda � 40GB 10k Raptor with Ubuntu 10.10 installed
/dev/sdb � 500GB HDD formatted to ext4
/dev/sdc � 500GB HDD split up as follows:
/dev/sdc1 � 80gb NTFS partition with Win7 installed
/dev/sdc1 � Remaining drive space NTFS but nothing on it yet
Grub2 refuses to detect that Windows is installed on the 3rd HDD. I've googled and spent hours trying all sorts of things to get it to detect it and add it to my boot menu.
If I disconnect all drives except the Windows drive it boots up straight into Win7, so it's healthy and happy. (as healthy and happy as Windows can be, I need it for work purposes only!)
Does anyone have any tips on what would be the best method to force grub to realise that Windows is sitting there?
As far as I understand, the Win7 partition should be (hd2,1) � does that sound right to you?
I haven't tried booting off an Ubuntu CD and re-installing grub, since I can get into Linux and all the guides seem to be about how to restore grub after a Windows install eats it...

My current setup has the following partition:
sda1: ubuntu 32-bits
sad2: ubuntu 64-bits
sad3: ext3 system for personal storage
sda4: swap
My idea is to format my sda2 to become ntfs and install a windows xp system.., my question is how this could affect my current grub2 config since the MBR loads from sda1?

I recently installed Ubuntu Netbook Remix (10.04) on my brother's Acer Aspire One (751h) netbook, set up to dual boot with XP Professional. The initial install was successful, with both OS's booting correctly. However, after a series of updates and module builds (this machine has the Poulsbo chipset, still somewhat of a mess), Grub2 is now unable to boot XP, displaying the error "Operating system not found."
To be clear, grub works properly (aside from not booting XP), so the MBR is intact, although I've rerun grub-install to be safe. Restoring the windows MBR (using testdisk) boots XP happily, but of course ignores the ubuntu installation. I also had testdisk rebuild the NTFS boot sector, to no change - grub still doesn't work, the windows MBR does. Using the grub console, I can "root (hd0,1)" and see files on the XP partition, but "chainloader +1; boot" again fails with the same error. The ubuntu install can likewise mount the NTFS partition with no problems.
Given the fact that switching the MBR fixes the issue, I'm suspecting a Grub2 configuration problem. However, the simplicity of "root (hd0,1); chainloader +1; boot" leaves me stumped as to what that could be. Also, the error text "Operating system not found" is suspiciously identical to my BIOS's error message when attempting to boot from a non-bootable medium (as I found out while attempting to make a bootable usb stick with my mac).

I installed Debian 8.2 first, then Windows 10 over it (I know, backwards, but I didn't wish to lose my customizations on Debian up to that point, and didn't realize until later that I wanted to Dual Boot). Running from a LiveCD of Debian 8.2:
Code: Select allsudo fdisk -l
Device - Start - End - Sectors - Size - Type
/dev/sda1 - 2048 - 116211711 - 116209664 - 55.4G - Linux filesystem
/dev/sda2 - 116211712 - 116244479 - 32768 - 16M - Microsoft reserved
/dev/sda3 - 116244480 - 232421375 - 116176896 - 55.4G - Microsoft basic data
/dev/sda4 - 232421376 - 234440703 - 2019328 - 986M - EFI System
[code]...
That's where I am stuck. I'm a bit new to Debian & Linux still and I've never dabbled with Grub2, I imagine I can't mount /dev/sda4 because in chrooted into /dev/sda1 and it can't see /dev/sda4 at this point (what I'm thinking anyway). So I try:
Code: Select allroot@debian:/# fdisk -l
fdisk: cannot open /proc/partitions: No such file or directory/I imagine that's what it is, but I don't know a way around that. I want to dual boot Windows 10 & Debian 8.2 on a UEFI (or EFI?) system with a GPT Disk. No guide I have found for fixing Grub2 or getting Dual Booting working with Debian then Windows installed have covered both things at the same time. I just have to be special I guess.

a server at work has been accessed through the desktop environment as root. I know this is a risk and since I have never done it before I was wondering if there are any files created by the desktop that could compromise the system and how could I clean it up.

I have been frustrated attempting to get Grub2 to boot a Debian Live system from hard disk. Have set aside a 4gb partition /dev/sda1 to contain the Debian Live and some other recovery tools. I actually have them all working from a 4gb USB stick successfully, but getting it to work on my HDD has proved challenging. On USB, I have PartedMagic, Gparted, Grml, and of course my standard 6.01 Squeeze. I have also managed to get the Debian Live booting from that USB stick. Very slick.
However, I can NOT get Debian Live to boot from my HDD; altho all of the others above boot fine. Have tried it two ways - one using an iSO image, which is how it is done on my USB stick. The other attempt is to copy the entire contents of the ISO to a directory.
Here are my directory structures:
debian_live_gnome_squeeze_i386- contains the following: debian-live-6.0.1-i386-gnome-desktop.iso initrd.gz initrd.img vmlinuz which is how it is laid out on my USB stick debian_live - contains the files from the ISO image The error I get is something like "panic unable to find live filesystem" My grub.cfg snippet for the two methods I have tried - the 2nd menuentry is similar to how it works on the USB stick.
menuentry "Debian 6.01 Live (on /dev/sda1)" {
insmod part_msdos
insmod ext2
set root=(hd0,msdos1)
[code]....
Probly don't really need to get it working since PartedMagic can do almost everything I need for recovery and I can use the USB for reinstall or whatever else.

i initilally installed ubuntu 9.10 then installed windows 7 ,then i recovered grub2 using livecd as told in the post [URL] i did "sudo update-grub" and got windows 7 menu entry but when i select that entry windows 7 does not load but the grub2 is reloaded again.
i cant boot to windows 7.
Windows 7 have 100 mb partition "System Reserved" the grub2 points to that partition but still windows 7 not loaded.
sudo fdisk -l

I installed Fedora 15, which was my first real departure from Debian based Linux OSs. I absolutely love the new Gnome 3, and was able to configure F15 to work as I wanted it to. On rebooting I realized that there was no boot loader screen, that F15 just booted and didn't give me a choice as to which OS I wanted to use. Eventually I was able to configure grub to let me see the boot loader and added my old boot loader as a choice. This worked well, maybe not a perfect solution, but it worked. This weekend I installed LMDE (Linux Mint Debian Edition) to another HDD. LMDE uses grub2 and after the install F15 was not recognized.
Two questions: Is there a way for grub2 to see F15? or Can F15 be installed using grub2? I really don't mind re-installing from scratch.

I want to load grub2 from grub4dos.I want to load directly the grub2 core. I know how to load first 512 bytes from some patition by chainloader and load grub2, but what I need is to load directly grub2 core without passing by bootstriping code (first 512 bytes).So, my first boot manager is grub4dos, then I can load grub2 and later I load Ubuntu. But I think I have to edit --set-root
What I dont know is how.
In hdd 0,7 (sda8) I have Ubuntu 10.10 and /boot/grub/core.img is in sda8 (hd0.7)
I tried this way:
Code:
title grub2
find --set-root /boot/grub/core.img
kernel /boot/grub/core.img
